  • Mounting base pad means for semiconductor devices and method of preparing same
    Patent number: 4853763
    Abstract: A mounting pad means for use in combination with solid-state semiconductive translating devices and including a base pad with flange walls extending from said base pad, and with device mounting pad means being secured to the surface of the base pad and comprising a thin layer of silicone base rubber. The base pad an flange walls are formed of a generally rigid laminate with a core having outer metal foil layers disposed on opposite surfaces thereof, and wherein the core is composed of a thin layer of silicone base rubber.
    Type: Grant
    Filed: December 22, 1986
    Date of Patent: August 1, 1989
    Assignee: The Bergquist Company
    Inventors: David C. DeGree, Dallas R. Humphrey, Carl R. Bergquist, Roger A. West

  • Mounting pad with tubular projections for solid-state devices
    Patent number: 4602125
    Abstract: A thermally conductive electrically insulative laminate for use as a mounting pad and electrical chassis barrier for use with solid-state electronic devices. The pad includes a number of bores with tubular projections extending outwardly therefrom for insulatively protecting the shanks of the mounting screws, bolts or other conductive materials from contact with the substrate. Additionally, the tubular projections are provided with radially extending retention burrs for mechanically holding the mounting pad in place on a substrate pending actual mounting of a semiconductor device thereon.
